Overview

The ECOWITT WH51 is designed as a wireless soil moisture sensor that works with compatible gateways or consoles. It comes as an accessory, not a standalone device, so pairing with a GW1000 or GW1100 gateway unlocks the full monitoring experience across your ECOWITT system.

How it works

When fully inserted into soil, the WH51 measures moisture and transmits readings to your Ecowitt setup in about 72 seconds. After you configure Wi‑Fi, you can view live data on WS View Plus or the Ecowitt app, keeping soil conditions in view whether you’re at home or away.

  • Reliable wireless sensing with a modern sensor chip for timely updates
  • Channel names can be edited on the gateway site or the Ecowitt platform
  • Supports uploading to the Ecowitt weather server for graphs and history downloads

Compatibility and expansion

The GW1100 gateway can support up to eight WH51 sensors. When paired with Weather Station Consoles HP2551, HP3500, or HP3501, you can view up to eight channels of soil moisture data in real time on a display. If you use Console WH0291, readings will appear on the display only.

  • Scale up with multiple sensors for larger spaces or multiple beds
  • Display options vary by console, enabling in-situ viewing or remote monitoring

Indoor & outdoor use

Encased in an IP66‑rated housing, the WH51 is suited for indoor pots, outdoor planters, lawns, gardens, and fields. It is designed to measure soil moisture and should be placed in appropriate soil types for accurate readings.

Notes before purchase: The WH51 cannot display soil humidity on its own and requires a gateway or console. Regional frequency varies: NA 915MHz; Europe 868MHz; other regions 433MHz.
